Wet and dry dual-purpose multifunctional sewage treatment equipment

Abstract

The invention provides wet and dry dual-purpose multifunctional sewage treatment equipment, which comprises an incubation bin, a biogas heating bin and a secondary incubation bin, a hopper and an auger device are arranged at the top of the incubation bin, a feeding port is formed in one side of the auger device, the hopper corresponds to the feeding port, and a pressing film is arranged on the surface of the incubation bin; an electric heater and a methane furnace are arranged in the methane heating bin, one end of the electric heater and one end of the methane furnace are connected with the top of the hatching bin through a methane conveying pipe, one end of the methane heating bin is connected with an exhaust channel, and the exhaust channel is communicated with the outside; a slag outlet pipe is arranged at the bottom of the second-stage incubation bin, one end of the slag outlet pipe is connected with a slag return pipe, and the slag return pipe extends to the feeding port; the sewage treatment equipment disclosed by the invention has the characteristics of convenience in feeding, thorough incubation and no crusting, secondary pollution in excrement treatment is avoided, treated solid residues and liquid do not generate odor, the treated solid residues and liquid are recycled as organic fertilizer resources, and zero emission and zero pollution in sewage treatment are achieved.

Description

technical field [0001] The invention relates to the technical field of energy-saving sewage treatment equipment, in particular to a wet and dry dual-purpose multifunctional sewage treatment equipment. Background technique [0002] The equipment currently used by users in the market: such as high-temperature aerobic fermentation process, for example, utility model patent: ZL201420576031.7, which discloses a non-powered self-stirring shell breaking anaerobic fermentation device. [0003] The above technologies have requirements for the dry humidity of the feces, that is, the moisture content and the slag content of the feces, when the feces to be treated are treated. The moisture content of feces in the high-temperature aerobic process is about 65%, and the treatment and operation costs are expensive. Each device consumes about 600 degrees of electricity per day, and the various costs per ton range from 100 to 200 yuan. Odor from secondary pollution sources is generated durin...
